Post-Disaster Restoration Strategy Using Multi-Resource Collaboration Based on Multi-Port Mobile Emergency Vehicle

Abstract

Due to the limitations of self-powered form, existing mobile emergency vehicles (MEV) have drawbacks of high energy consumption, poor continuous power supply capability, and high vacancy rates. Breaking the traditional paradigm that MEV can only connect to the power grid from a single port and self-powered, a multi-port mobile emergency vehicles (MPMEV) is proposed. On this basis, combining MPMEV’s operational characteristics with multi-port interconnection capabilities, a post-disaster power supply restoration strategy by collaborating MPMEV and multi-resource is designed. Initially, the topology structure and various operational modes of MPMEV are elaborated, and a mathematical model for various operational modes of MPMEV is established. Moreover, the impact of the post-disaster traffic network impedance on MPMEV scheduling is studied, and a mobile path characterization method suitable for the dynamic fusion of traffic and power networks is developed. Subsequently, taking into account the dynamic reconfiguration of the distribution network, a restoration strategy by collaborating MPMEV, distributed generator, tie switch and manual repairs is designed with multi-objectives such as investment costs, load outage losses, and renewable energy utilization rates. Finally, the effectiveness and advancement of the proposed MPMEV and collaborative restoration strategy are validated based on the IEEE 33-node systems.
